Astronomy midterm question: Venus setting while Jupiter rising at night?

Astronomy 210 Midterm 1, spring semester 2020
Cuesta College, San Luis Obispo, CA

The following excerpt describes a night where Venus is setting while Jupiter is rising[*]:

Let me try to recall what has happened, the amusing and strange, and sad and terrible scenes witnessed in these last few days. On my first night at sea, I watched Venus slowly sinking into the sea, and Jupiter rising...

Discuss a plausible time (around sunset, midnight, or sunrise) that these two planets would be observed in San Luis Obispo, CA, and how you know this. Support your answer using a diagram showing the positions of the sun, Venus, Jupiter, Earth, and an observer on Earth.

[*] J.C., "Wrecked--A Week on Sable Island," The Canadian Methodist Magazine, vol. XV (January-June 1882), p. 73.

Solution and grading rubric:

• p:
  Complete diagram and reasoning where observer on Earth must be at sunset to watch Venus (in an inner orbit) setting while Jupiter (in an inner orbit) rises in the east.
• r:
  Nearly correct (explanation weak, unclear or only nearly complete); includes extraneous/tangential information; or has minor errors. Typically diagram and/or supporting argument is contradictory or incomplete.
• t:
  Contains right ideas, but discussion is unclear/incomplete or contains major errors. Still has Venus in an inner orbit and Jupiter in an outer orbit around the sun.
• v:
  Limited relevant discussion of supporting evidence of at least some merit, but in an inconsistent or unclear manner. Some attempt at diagram(s), but no clear indication of observer/horizon on Earth and/or placement of inner planets. Typically misplaces Venus and Jupiter in their relative inner/outer orbits around the sun, or has Venus and Jupiter orbiting Earth.
• x:
  Implementation/application of ideas, but credit given for effort rather than merit.
• y:
  Irrelevant discussion/effectively blank.
• z:
  Blank.

Cuesta College, San Luis Obispo, CA

The locations of Mercury, Venus, and Earth are shown in the diagram below (not to scale, and orbits have been simplified as circles instead of ellipses).


At sunrise, Venus will be:
(A) low over the east horizon.
(B) somewhere high up in the sky.
(C) low over the west horizon.
(D) not visible in the sky.

Correct answer (highlight to unhide): (A)

If a line is drawn from Earth to the sun, the observer at sunrise (6 AM) is located perpendicular to that line.


Everything above that line would be above the horizon, such that Venus will be visible at sunrise, low over the east horizon.

Astronomy midterm question: 12 hours between Mercury setting and Venus rising?

Astronomy 210 Midterm 1, fall semester 2019
Cuesta College, San Luis Obispo, CA

An astronomy question on an online discussion board was asked and answered[*]:

J.F.: Can an observer ever witness Mercury setting at the same time while Venus is rising?
rzfr: No, that is impossible. It will take about 12 hours between Mercury setting and Venus rising.

Discuss why it would take about 12 hours between Mercury setting and Venus rising for an observer in San Luis Obispo, CA, and how you know this. Support your answer using a diagram showing the positions of the sun, Mercury, Venus, Earth, and an observer on Earth.

[*] answers.yahoo.com/question/index?qid=20090328072648AALZoVS.

Solution and grading rubric:

• p:
  Complete diagram and reasoning includes the following explanations for why there would be about 12 hours between Mercury setting and Venus rising:
  1. places observer on Earth at sunset to watch Mercury (in an inner orbit) setting in the west; and
  2. places observer on Earth at sunrise to watch Venus (in an inner orbit) rising in the east.
• r:
  Nearly correct (explanation weak, unclear or only nearly complete); includes extraneous/tangential information; or has minor errors. Typically diagram is correct, but supporting argument is contradictory or incomplete. May have placed Mercury to rise at sunrise and placed Venus to set at sunset.
• t:
  Contains right ideas, but discussion is unclear/incomplete or contains major errors. Still has Mercury and Venus along inner orbits around the sun.
• v:
  Limited relevant discussion of supporting evidence of at least some merit, but in an inconsistent or unclear manner. Some attempt at diagram(s), but no clear indication of observer/horizon on Earth and/or placement of inner planets. Typically misplaces Mercury and Venus in their relative outer/inner orbits around the sun.

Astronomy midterm question: Jupiter, not Venus low in the west at dawn

Astronomy 210 Midterm 1, spring semester 2019
Cuesta College, San Luis Obispo, CA

An astronomy question on an online discussion board was asked and answered[*]:

deanmajiet65: Just before dawn, I saw a planet in the sky in the west. Is it Jupiter or Venus?
Rich: It's not Venus. You were facing west, so that was Jupiter.

Discuss why this planet could not be Venus, and would have to be Jupiter for an observer in San Luis Obispo, CA, and how you know this. Support your answer using a diagram showing the positions of the sun, Venus, Jupiter, Earth, and an observer on Earth.

[*] answers.yahoo.com/question/index?qid=20090727104303AA5cFyR.

Solution and grading rubric:

• p:
  Complete diagram and reasoning includes the following explanations for how it is possible for an observer on Earth to be able to see Jupiter, but not Venus in the west at dawn:
  1. places observer on Earth at dawn (or some time after midnight but before sunrise), with east and west horizons clearly indicated; and
  2. is able to place Jupiter (in an outer orbit) such that it is visible above the west horizon for this observer, and also indicates how Venus (in an inner orbit) can only be seen in the east horizon if it is visible at all at dawn.
• r:
  Nearly correct (explanation weak, unclear or only nearly complete); includes extraneous/tangential information; or has minor errors. Typically diagram is correct, but supporting argument is contradictory or incomplete.
• t:
  Contains right ideas, but discussion is unclear/incomplete or contains major errors. May have an observer at sunset instead of sunrise, and/or switched east/west horizons; but still has Jupiter and Venus along outer and inner orbits around the sun, respectively.
• v:
  Limited relevant discussion of supporting evidence of at least some merit, but in an inconsistent or unclear manner. Some attempt at diagram(s), but no clear indication of observer/horizon on Earth and how placement of outer and inner planets would (or would not) be visible at dawn in the west. Typically misplaces Jupiter and Venus in their relative outer/inner orbits around the sun.
• x:
  Implementation/application of ideas, but credit given for effort rather than merit.

Astronomy midterm question: earlier shift of Jupiter's rising time?

Astronomy 210 Midterm 1, fall semester 2018
Cuesta College, San Luis Obispo, CA

The following description of Jupiter was given in a science magazine[*]:

At the beginning of this month Jupiter rises around midnight. At the end of this month Jupiter rises around 10 PM.

Discuss how this earlier shift of Jupiter's rising time over the course of a month would be plausible for an observer in San Luis Obispo, CA, and how you know this. Support your answer using diagrams showing the positions of the sun, Jupiter, Earth, and an observer on Earth.

[*] Astronomical Notes," Scientific American, vol. 43 no. 235 (July 3, 1880), p. 11, books.google.com/books?id=6ok9AQAAIAAJ&dq.

Solution and grading rubric:

• p:
  Complete diagram and reasoning includes the following explanations for an observer on Earth looking at Jupiter:
  1. Jupiter's position in its orbit around the sun is "ahead of" Earth's position in its orbit around the sun such that the observer on Earth at midnight is able to see Jupiter rising from the east horizon, and
  2. a few months later, Earth has "caught up" to Jupiter (but not yet at superior conjunction) such the observer on Earth will see Jupiter rising from the horizon at an earlier time.
• r:
  Nearly correct (explanation weak, unclear or only nearly complete); includes extraneous/tangential information; or has minor errors. May have Jupiter highest overhead at midnight (at superior conjunction) for the earlier drawing, and then Earth slightly ahead of Jupiter for the later drawing such that Jupiter is overhead at 10 PM.
• t:
  Contains right ideas, but discussion is unclear/incomplete or contains major errors. May have geocentric model of Jupiter orbiting Earth, or Earth staying still while Jupiter moves relative to Earth around sun, or observer/times on Earth are in wrong positions.
• v:
  Limited relevant discussion of supporting evidence of at least some merit, but in an inconsistent or unclear manner. Some attempt at diagram(s), but no clear indication of observer/times on Earth and how relative motions of Earth and Jupiter would cause the earlier shift of Jupiter's rising time.
• x:
  Implementation/application of ideas, but credit given for effort rather than merit.

Cuesta College, San Luis Obispo, CA

The locations of Earth, Mars, and Jupiter are shown in the diagram below (not to scale, and orbits have been simplified as circles instead of ellipses).


Jupiter is __________ retrograde motion.
(A) about to start.
(B) in the middle of.
(C) just completing.

Correct answer (highlight to unhide): (C)


Retrograde motion occurs for Jupiter when the sun, Earth, and Jupiter are aligned (Mars in opposition). Drawing in lines from the sun to Earth and the sun to Jupiter indicates that Earth (which travels faster along its inner orbit), has already overtaken Jupiter (which travels slower along its outer orbit), thus Jupiter has already completed its retrograde motion.

Astronomy quiz question: planets visible at sunset?

Astronomy 210 Quiz 2, spring semester 2018
Cuesta College, San Luis Obispo, CA

The locations of Saturn, Earth, and Jupiter are shown in the diagram below (not to scale, and orbits have been simplified as circles instead of ellipses).


Which planet(s) will be visible at sunset?
(A) Saturn.
(B) Jupiter.
(C) (Both of the above choices.)
(D) (Neither of the above choices.)

Correct answer (highlight to unhide): (C)

If a line is drawn from Earth to the sun, the observer at sunset (6 PM) is located perpendicular that line. Since Saturn and Jupiter are both above that horizon line, they will both be visible at that time, where Saturn would be low over the east horizon, and Jupiter would be low over the west horizon.)
